Description
Product Description
The N20 Metal Gear Motor (200 RPM) is a compact, high-performance DC geared motor designed for precision motion control in robotics, automation, and DIY engineering applications. Built with a durable all-metal gearbox, this motor delivers reliable torque, smooth operation, and long service life even under continuous use.
With its small footprint and lightweight design, the N20 motor is ideal for space-constrained projects such as line follower robots, obstacle avoidance robots, mini CNC mechanisms, smart locks, camera sliders, and educational robotics kits. The 200 RPM output speed provides an excellent balance between speed and torque, making it suitable for controlled movement and accurate positioning.
The motor operates on low DC voltage, allowing easy integration with Arduino, ESP32, Raspberry Pi, motor driver modules (L298N, TB6612FNG, DRV8833) and battery-powered systems. The metal gear assembly ensures improved strength and resistance to wear compared to plastic gear motors, making it dependable for both prototyping and production-level designs.
